Authentication: Cache system not on main thread

This is error very sporadic, it happens about 20% of the time but it is pretty serious since it causes the app to crash. I have tried wrapping SpotifyAuth.login in a try catch but this error seems to be lower level on the Objective-C side.

Doing the following fixed the issue for me:

Find [delegate.window.rootViewController presentViewController: controller animated:YES completion:nil]; in SpotifyAuth.m and replace it with:

dispatch_async(dispatch_get_main_queue(), ^{ //Present the webView over the rootView [delegate.window.rootViewController presentViewController: controller animated:YES completion:nil]; });
